Let's divide 285151 by 7
We want to divide 285151 by 7.

On to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 7

On to step 2:
If we divide 28 by 7, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 28 from 28 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 7

Going ahead to step 3:
If we divide 5 by 7, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 7

On to step 4:
If we divide 51 by 7, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 407.0
If we subtract 49 from 51, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 7

Step 5:
The number 7 fits into 25 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4073.0
The remainder is 4 after subtracting 21 from 25.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Advancing to step 6:
If we divide 41 by 7, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 40735.0
Subtracting 35 from 41 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 40735.8
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40735.85
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 40735.857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 40735.8571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 40735.85714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 40735.857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 40735.8571428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 40735.85714285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 40735.85714285 with a remaining 5e-09.
